High level overview​

The Mithril team completed decentralizing the signature orchestration of the Mithril network. They also completed refactoring the Prometheus metrics in the signer and started implementing them in the aggregator. Additionally, the team kept working on supporting the new Pythagoras Mithril era and created the new distribution pre-release 2442.0-pre.

Finally, they kept implementing optimizations on the node logs and enhanced the release creation workflow in the CI.

High level summary​

  • More anchor data hash checks were added to cardano-cli commands.
  • Support to create certificates that can register and delegate stake.
  • Moved various era agnostic commands to the top level of cardano-cli.
  • Added Cardano.Api.Tx.Compatible to cardano-api which allows the creation of simple unbalanced transactions that can submit protocol updates in any era.

Overview of [sprint 73][sprint-73]​

Ouroboros-Network-0.18 release​

We released ouroboros-network-0.18. The main features are:

  • integration with typed-protocols-0.3
  • cardano-client library doesn't depend on the non-p2p stack
  • We expose connectToWithMux family of functions in ouroboros-network which give access to the underlying [Mux handle][mux-handle].
  • Added NodeToClientV_19: to support the new GetLedgerPeerSnapshot query in local-state-query mini-protocol [ouroboros-consensus#1067].

See full [the list of PRs][ouroboros-network-0.18] included in this release. ouroboros-network-0.18 was integrated with ouroboros-consensus ([ouroboros-consensus#1223])

Tx-Submission​

We continued working on tx-submission and monitoring its performance.

Ouroboros-Network - Mithril Design​

We internally discussed how to support the [Mithril design][cip#137]. In In the near future, we will be able to socialise the report we've been working on.

Code Refactoring​

We reorganised some of our substysems to use qualified imports with simplified names:

  • [ouroboros-network#4990] (connection-manager, inbound-governor)
  • [ouroboros-network#4997] (network-mux)

We also removed deprecated APIs in [ouroboros-network#4998]sim#182]

High level summary​

We implemented the remaining improvements and fixes discovered in Conway, to be fixed during the bootstrap period:

* protection against deposit loses
* ensuring that DReps exist before delegating
* updates to SPO vote threshold calculation
* improved well-formedness check

Additionally, we added two new rules: Mempool and HardFork, that will allow us to flexibly add processing logic in the future. We also dropped pointers for Conway and enhanced predicate failure reporting for pre-Conway eras.

Finally, we added more tests - both unit and conformance tests.

  • pull-4647 - Drop pointers from UMap in Conway
  • pull-4642 - Mempool rule
  • pull-4553 - Address issues in auto-generated CDDL specification
  • pull-4650 - Check ppuCoinsPerUTxOBytes well-formedness
  • pull-4648 - Updated conformance to work with new MAlonzo types
  • pull-4653 - Improve color output in Imp spec
  • pull-4603 - Add more tests for voting behaviour
  • pull-4639 - Prevent non-registered return accounts for proposals' deposits and TreasuryWithdrawals
  • pull-4632 - Export Unsafe constructors for TxBody, TxBodyRaw and MemoBytes
  • pull-4654 - Add applyTxOpts to ApplyTx
  • pull-4657 - HardFork rule
  • pull-4659 - Change how SPO votes are counted
  • pull-4660 - UTXO conformance with Babbage transactions
  • pull-4652 - Ensure dreps exist prior to delegation
